i cannot use the top address bar to search.it just comes up nothing found.however if i clip the search button which brings m.s.n search on left collumn it works. history;- i am running xp pro -tiscali broadband i have received 'trojan byte size verify' appearing on pc.i thought i had destroyed through norton and 'spybot', well when i run full scan nothing shows up. also i keeps getting a message box appear saying search180 assistant has been removed by a third party,would you like to reinstall/remove all trace or remind me later??? i have checked regedit and the settings in the advance tab and they seem alright. the opther thing that happens is that the 'red' circle with line accross keeps flashing as if the sytem is trying to refresh.
